Classical compound

Last updated

Classical compounds and neoclassical compounds are compound words composed from combining forms (which act as affixes or stems) derived from classical Latin or ancient Greek roots. New Latin comprises many such words and is a substantial component of the technical and scientific lexicon of English and other languages, including international scientific vocabulary. For example, bio- combines with -graphy to form biography ("life" + "writing/recording").


Source of international technical vocabulary

Classical compounds represent a significant source of Neo-Latin vocabulary. Moreover, since these words are composed from classical languages whose prestige is or was respected throughout the Western European culture, these words typically appear in many different languages. Their widespread use makes technical writing generally accessible to readers who may only have a smattering of the language in which it appears.

Not all Western European languages have been equally receptive to classical technical compounds. German and Russian, for instance, have historically attempted to create their own technical vocabularies from native elements. Usually, these creations are German and Russian calques on the international vocabulary, such as Wasserstoff and "водород" (vodoród) for hydrogen . Like any exercise in language prescription, this endeavour has been only partially successful, so while official German may still speak of a Fernsprecher, public telephones will be labelled with the internationally recognized Telefon.

Formation, spelling, and pronunciation

These words are compounds formed from Latin and Ancient Greek root words. Ancient Greek words are almost invariably romanized (see transliteration of Ancient Greek into English). In English:

Thus, for example, Ancient Greek σφιγξ becomes English (and Latin) sphinx . Exceptions to these romanizing rules occur, such as leukemia (leukaemia); compare leukocyte , also leucocyte. In Latin, and in the target languages, the Greek vowels are given their classical values rather than their contemporary values in demotic Greek.

Ancient Greek words often contain consonant clusters which are foreign to the phonology of contemporary English and other languages that incorporate these words into their lexicon: diphthong ; pneumatology , phthisis . The traditional response in English is to treat the unfamiliar cluster as containing one or more silent letters and suppress their pronunciation, more modern speakers tend to try and pronounce the unusual cluster. This adds to the irregularities of English spelling; moreover, since many of these words are encountered in writing more often than they are heard spoken, it introduces uncertainty as to how to pronounce them when encountered.

Classical compounds frequently vary their stressed syllable when suffixes are added: ágriculture, agricúltural. This also gives rise to uncertainty when these words are encountered in print. Once a classical compound has been created and borrowed, it typically becomes the foundation of a whole series of related words: e.g. astrology, astrological, astrologer/astrologist/astrologian, astrologism.

Mainstream medical and ISV pronunciation in English is not the same as Classical Latin pronunciation. Like Ecclesiastical Latin, it has a regularity of its own, and individual sounds can be mapped or compared. Although the Classical Latin pronunciation of venae cavae would be approximately /ˈwɛnˈkɑːw/ , the standard English medical pronunciation is /ˈvnˈkv/ .

History and reception

English began incorporating many of these words in the sixteenth century; geography first appeared in an English text in 1535. Other early adopted words that still survive include mystagogue , from the 1540s, and androgyne , from the 1550s. The use of these technical terms predates the scientific method; the several varieties of divination all take their names from Classical compounds, such as alectryomancy , divination by the pecking of chickens.

Not all English writers have been friendly to the inflow of Classical vocabulary. The Tudor period writer Sir John Cheke wrote:

I am of this opinion that our own tung should be written cleane and pure, unmixt and unmangeled with borrowing of other tunges; wherein if we take not heed by tiim, ever borowing and never paying, she shall be fain to keep her house as bankrupt.

and therefore rejected what he called "inkhorn terms".

Similar sentiments moved the nineteenth century author William Barnes to write "pure English," in which he avoided Greco-Latin words and find Anglo-Saxon equivalents therefor: for Barnes, the newly invented art of the photograph became a sun-print. Unlike this one, some of Barnes's coinages caught on, such as foreword , Barnes's replacement for the preface of a book. Later, Poul Anderson wrote a jocular piece called Uncleftish Beholding in a constructed language based on English which others have called "Ander-Saxon"; this attempted to create a pure English vocabulary for nuclear physics.

More recent developments

Many such words, such as thermometer , dinosaur , rhinoceros , and rhododendron , are thoroughly incorporated into the English lexicon and are the ordinary words for their referents. Some are prone to colloquial shortening; rhinoceros often becomes rhino. The binomial nomenclature of taxonomy and biology is a major source for these items of vocabulary; for many unfamiliar species that lack a common English name, the name of the genus becomes the English word for that life form.

In the metric system, prefixes that indicate multipliers are typically Greek in origin, such as kilogram, while those that indicate divisors are Latin, as in millimeter: the base roots resemble Greek words, but in truth are neologisms. These metric and other suffixes are added to native English roots as well, resulting in creations such as gigabyte . Words of mixed Latin and Greek lineage, or words that combine elements of the classical languages with English – so-called hybrid words – were formerly castigated as "barbarisms" by prescriptionist usage commentators; this disapproval has mostly abated. Indeed, in scientific nomenclature, even more exotic hybrids have appeared, such as for example the dinosaur Yangchuanosaurus . Personal names appear in some scientific names such as Fuchsia .

Classical compounds are sometimes used to lend grandeur or the impression of scientific rigour to humble pursuits: the study of cosmetology will not help anyone become an astronaut . Compounds along these models are also sometimes coined for humorous effect, such as odontopodology, the science of putting your foot into your mouth. These humorous coinages sometimes take on a life of their own, such as garbology , the study of garbage.

Some classical compounds form classical plurals, and are therefore irregular in English. Others do not, while some vacillate between classical and regular plurals.


There are hundreds of classical compounds in English and other European languages. As traditionally defined, they cannot stand alone as free words, but there are many exceptions to this rule, and in the late 20th century such forms are increasingly used independently: bio as a clipping of biography, telly as a respelt clipping of television. Most classical compounds translate readily into everyday language, especially nouns: bio- as ‘life’ -graphy as ‘writing, description’. Because of this, the compounds of which they are part (usually classical or learned compounds) can be more or less straightforwardly paraphrased: biography as ‘writing about a life’, neurology as ‘the study of the nervous system’. Many classical compounds are designed to take initial or final position: autobiography has the two initial or preposed forms auto-, bio-, and one postposed form -graphy. Although most occupy one position or the other, some can occupy both: -graph- as in graphology and monograph; -phil- as in philology and Anglophile. Occasionally, the same base is repeated in one word: logology the study of words, phobophobia the fear of fear.

Preposed and postposed

Prefixes include: aero- air, crypto- hidden, demo- people, geo- earth, odonto- tooth, ornitho- bird, thalasso sea. Many have both a traditional simple meaning and a modern telescopic meaning: in biology, bio- means ‘life’, but in bio-degradable it telescopes ‘biologically’; although hypno- basically means ‘sleep’ (hypnopaedia learning through sleep), it also stands for ‘hypnosis’ (hypnotherapy cure through hypnosis).

When a form stands alone as a present-day word, it is usually a telescopic abbreviation: bio biography, chemo chemotherapy, hydro hydroelectricity, metro metropolitan. Some telescoped forms can be shorter than the original classical compounds: gynie is shorter than gyneco- and stands for both gynecology and gynecologist; anthro is shorter than anthropo- and stands for anthropology.

Suffixes include: -ectomy cutting out, -graphy writing, description, -kinesis motion, -logy study, -mancy divination, -onym name, -phagy eating, -phony sound, -therapy healing, -tomy cutting. They are generally listed in dictionaries without the interfixed vowel, which appears however in such casual phrases as ‘ologies and isms’.


Some classical compounds are variants of one base.

Some are also free words, such as mania in dipsomania and phobia in claustrophobia.

Some are composites of other elements, such as encephalo- brain, from en- in, -cephal- head; and -ectomy cutting out, from ec- out, -tom- cut, -y, a noun-forming suffix that means "process of".


In Greek and Latin grammar, combining bases usually require a thematic or stem-forming vowel. In biography, from Greek, the thematic is -o-; in agriculture, from Latin, it is -i-. In English morphology, this vowel can be considered as an interfix: -o- , in miniskirt, the interfix -i- . It is usually regarded as attached to the initial base (bio-, mini-) rather than the final base (-graphy, -skirt), but in forms where it is conventionally stressed, it is sometimes considered as part of the final base (-ography, -ology). If the final element begins with a vowel (for example, -archy as in monarchy), the mediating vowel has traditionally been avoided (not *monoarchy), but in recent coinages it is often kept, sometimes accompanied by a hyphen (auto-analysis, bioenergy , hydroelectricity , not *autanalysis, *bienergy, *hydrelectricity).

Its presence helps to distinguish classical compounds like biography and agriculture from vernacular compounds like teapot and blackbird.


Generally, English has acquired its classical compounds in three ways: through French from Latin and Greek, directly from Latin and Greek, and by coinage in English on Greek and Latin patterns. An exception is schizophrenia, which came into English through German, and is therefore pronounced ‘skitso’, not ‘skyzo’.

The conservative tradition

From the Renaissance until the mid-20th century, the concept of derivational purity has generally regulated the use of classical compounds: Greek with Greek, Latin with Latin, and a minimum of hybridization. Biography is Greek, agriculture Latin, but television is a hybrid of Greek tele- and Latin -vision (probably so coined because the ‘pure’ form telescope had already been adopted for another purpose). Most dictionaries follow the Oxford English Dictionary in using combining form (comb. form) to label such classical elements, but the name is not widely known. In appendices to dictionaries and grammar books, classical compounds are often loosely referred to as roots or affixes: ‘a logo …, properly speaking, is not a word at all but a prefix meaning word and short for logogram, a symbol, much as telly is short for television’ (Montreal Gazette, 13 Apr. 1981). They are often referred to as affixes because some come first and some come last, but if they were affixes, a word like biography would have no base whatever. While affixes are grammatical (like prepositions), classical compounds are lexical (like nouns, adjectives, and verbs): for example, bio- translates as a noun (life), -graphy as a verbal noun (writing). They are also often loosely called roots because they are ancient and have a basic role in word formation, but functionally and often structurally they are distinct from roots: the -graph in autograph is both a root and a classical compound, while the -graphy in cryptography consists of root -graph- and suffix -y, and is only a classical compound.

Contemporary developments

Generally, classical compounds were a closed system from the 16th century to the earlier 20th century: the people who used them were classically educated, their teachers and exemplars generally took a purist's view on their use, contexts of use were mainly technical, and there was relatively little seepage into the language at large. However, with the decline of classical education and the spread of technical and quasitechnical jargon in the media, a continuum has evolved, with at least five stages:

Pure classical usage

In the older sciences, classical compounds are generally used to form such strictly classical and usually Greek compounds as anthocyanin, astrobleme, chemotherapy, chronobiology, cytokinesis, glossolalia, lalophobia, narcolepsy, osteoporosis, Pliohippus, sympathomimetic.

Hybrid classical usage

In technical, semitechnical, and quasitechnical usage at large, coiners of compounds increasingly treat Latin and Greek as one resource to produce such forms as accelerometer, aero-generator, bioprospector, communicology, electroconductive, futurology, mammography, micro-gravity, neoliberal, Scientology, servomechanism.

Hybrid classical/vernacular usage

In the later 20th century, many forms have cut loose from ancient moorings: crypto- as in preposed Crypto-Fascist and pseudo- as in pseudoradical; postposed -meter in speedometer, clapometer. Processes of analogy have created coinages like petrodollar , psycho-warfare , microwave on such models as petrochemical , psychology, microscope. Such stunt usages as eco-doom, eco-fears, eco-freaks, common in journalism, often employ classical compounds telescopically: eco- standing for ecology and ecological and not as used in economics. In such matters, precision of meaning is secondary to compactness and vividness of expression.

Combining forms as separate words

In recent years, the orthography of many word forms has changed, usually without affecting pronunciation and stress. The same spoken usage may be written micro-missile, micro missile, micromissile, reflecting the same uncertainty or flexibility as in businessman, business-man, business man. When used in such ways, classical compounds are often telescopic: Hydro substation Hydro-Electricity Board substation, Metro highways Metropolitan highways, porno cult pornography cult.

New classical compounds

The mix of late 20c techno-commercial coinages includes three groups of post- and non-classical forms: (1)Established forms: econo- from ‘economic’, as in econometric, Econo-Car, mini- from ‘miniature’, as in miniskirt, mini-boom, -matic from ‘automatic’, as in Adjustamatic, Instamatic , Stackomatic. (2) Less established forms, often created by blending: accu- from ‘accurate’, as in Accuvision ; compu- from ‘computer’, as in Compucorp; docu- from ‘documentary’, as in docudrama; perma- from ‘permanent’, as in permafrost and permaban; dura- from ‘durable’, as in Duramark. (3) Informal vernacular material in pseudo-classical form: Easibird , Healthitone , Redi-pak , Relax-A-Cizor (relax, exerciser).

Binational forms

Word forms exist for describing relations or interactions between two nations or societies, such as "Anglo-French" (England and France), Franco-Italian (France and Italy), Greco-Turkish (Greece and Turkey), Russo-Japanese (Russia and Japan), Sino-Cambodian (China and Cambodian), Americo-Liberian (the United States and the African nation of Liberia). In theory, at least, word forms exist to describe every conceivable pairing, although some (Peruvo-Ugandan? Papuo-Icelandic?) may tend more to the fabulous than the actually useful forms. Note that it could be argued that Franco-English, Italo-French, Turco-Grecian, and so forth are equally valid ways of describing the relationship or interactions. The term Afro-American was formerly used to describe a Black American, but now it is deemed more politically correct not to use the Afro- combining form and instead, the term African American is used.

Similar systems

In East Asia, a similar role to Latin and Greek has been played by Chinese, with non-Chinese languages both borrowing a significant number of words from Chinese and using morphemes borrowed from Chinese to coin new words, particularly in formal or technical language. See Sino-Japanese vocabulary, Sino-Korean vocabulary, and Sino-Vietnamese vocabulary for discussion.

The coinage of new native terms on Chinese roots is most notable in Japanese, where it is referred to as wasei kango (和製漢語, Japanese-made Chinese-words). Many of these have been subsequently borrowed into Chinese, Korean, and Vietnamese, with the same (or corresponding) characters being pronounced differently according to language, just as happens in European languages – compare English biology and French biologie.

For example, 自動車 (Japanese jidōsha, Korean jadongcha, Mandarin zìdòngchē) is a Japanese-coined word meaning “automobile”, literally self-move-car; compare to auto (self) + mobile (moving).

Latin Indo-European language of the Italic family

Latin is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally spoken in the area around Rome, known as Latium. Through the power of the Roman Republic, it became the dominant language in Italy, and subsequently throughout the western Roman Empire. Latin has contributed many words to the English language. In particular, Latin roots are used in English descriptions of theology, the sciences, medicine, and law.

In linguistics, morphology is the study of words, how they are formed, and their relationship to other words in the same language. It analyzes the structure of words and parts of words, such as stems, root words, prefixes, and suffixes. Morphology also looks at parts of speech, intonation and stress, and the ways context can change a word's pronunciation and meaning. Morphology differs from morphological typology, which is the classification of languages based on their use of words, and lexicology, which is the study of words and how they make up a language's vocabulary.

A loanword is a word adopted from one language and incorporated into another language without translation. This is in contrast to cognates, which are words in two or more languages that are similar because they share an etymological origin, and calques, which involve translation.

-logy is a suffix in the English language, used with words originally adapted from Ancient Greek ending in -λογία (-logia). The earliest English examples were anglicizations of the French -logie, which was in turn inherited from the Latin -logia. The suffix became productive in English from the 18th century, allowing the formation of new terms with no Latin or Greek precedent.

Ancient Greek Forms of Greek used from around the 9th century BC to the 6th century AD

Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around the 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek, Dark Ages, the Archaic period, and the Classical period.

International scientific vocabulary (ISV) comprises scientific and specialized words whose language of origin may or may not be certain, but which are in current use in several modern languages. The name "international scientific vocabulary" was first used by Philip Gove in Webster’s Third New International Dictionary (1961). As noted by Crystal, science is an especially productive field for new coinages.

Sino-Japanese vocabulary or kango refers to that portion of the Japanese vocabulary that originated in Chinese or has been created from elements borrowed from Chinese. Some grammatical structures and sentence patterns can also be identified as Sino-Japanese. Sino-Japanese vocabulary is referred to in Japanese as kango (漢語), meaning 'Chinese words'. Kango is one of three broad categories into which the Japanese vocabulary is divided. The others are native Japanese vocabulary and borrowings from other, mainly Western languages (gairaigo). It is estimated that approximately 60% of the words contained in a modern Japanese dictionary are kango, but they comprise only about 18% of words used in speech.

Esperanto etymology, including vocabulary and grammatical forms, derives primarily from the Romance languages, with lesser contributions from Germanic. The language occupies a middle ground between "naturalistic" constructed languages such as Interlingua, which borrow words en masse from their source languages with little internal derivation, and a priori conlangs such as Solresol, in which the words have no historical connection to other languages. In Esperanto, root words are borrowed and retain much of the form of their source language, whether the phonetic form (eks- from international ex-,vualo from French voile) or orthographic form (teamo and boato from English team and boat,soifo from French soif). However, each root can then form dozens of derivations which may bear little resemblance to equivalent words in the source languages, such as registaro (government), which is derived from the Latinate root reg but has a morphology closer to German or Russian.

The Greek language has contributed to the English vocabulary in five main ways:

In phonology, epenthesis means the addition of one or more sounds to a word, especially to the interior of a word. The word epenthesis comes from epi- "in addition to" and en "in" and thesis "putting". Epenthesis may be divided into two types: excrescence for the addition of a consonant, and for the addition of a vowel, svarabhakti or alternatively anaptyxis. The opposite process, where one or more sounds are removed, is referred to as elision.

English is a Germanic language, with a grammar and a core vocabulary inherited from Proto-Germanic. However, a significant portion of the English vocabulary comes from Romance and Latinate sources. A portion of these borrowings come directly from Latin, or through one of the Romance languages, particularly Anglo-Norman and French, but some also from Italian, Portuguese, and Spanish; or from other languages into Latin and then into English. The influence of Latin in English, therefore, is primarily lexical in nature, being confined mainly to words derived from Latin roots.

In linguistics, a stem is a part of a word responsible for its lexical meaning. The term is used with slightly different meanings and would depend on the morphology of the language in question. In Athabaskan linguistics, for example, a verb stem is a root that cannot appear on its own, and that carries the tone of the word. Athabaskan verbs typically have two stems in this analysis, each preceded by prefixes.

Dutch orthography uses the Latin alphabet. The spelling system is issued by government decree and is compulsory for all government documentation and educational establishments.

The word base of Esperanto was originally defined in Unua Libro, published by L. L. Zamenhof in 1887. It contained around 900 root words. The rules of the language allow speakers to borrow words as needed, recommending only that they look for the most international words, and that they borrow one basic word and derive others from it, rather than borrowing many words with related meanings. In 1894, Zamenhof published the first Esperanto dictionary, Universala vortaro, which was written in five languages and supplied a larger set of root words.

Ancient Greek phonology is the reconstructed phonology or pronunciation of Ancient Greek. This article mostly deals with the pronunciation of the standard Attic dialect of the fifth century BC, used by Plato and other Classical Greek writers, and touches on other dialects spoken at the same time or earlier. The pronunciation of Ancient Greek is not known from direct observation, but determined from other types of evidence. Some details regarding the pronunciation of Attic Greek and other Ancient Greek dialects are unknown, but it is generally agreed that Attic Greek had certain features not present in English or Modern Greek, such as a three-way distinction between voiced, voiceless, and aspirated stops ; a distinction between single and double consonants and short and long vowels in most positions in a word; and a word accent that involved pitch.

Medical terminology is language used to precisely describe the human body including its components, processes, conditions affecting it, and procedures performed upon it. Medical terminology is used in the field of medicine.

English prefixes are affixes that are added before either simple roots or complex bases consisting of (a) a root and other affixes, (b) multiple roots, or (c) multiple roots and other affixes. Examples of these follow:

Wago are native Japanese words, meaning those words in Japanese that have been inherited from Old Japanese, rather than being borrowed at some stage. Together with kango (漢語) and gairaigo (外来語), they form one of the three main sources of Japanese words. They are also known as yamato kotoba.
